60Hz SST flickering has been identified as an issue with non-standard display timings exhibited by the AOC U2868PQU panel on certain AMD Radeon graphics cards. A software workaround has been implemented in the AMD Catalyst 14.9 driver to resolve the display timing issues with this display

Users seeing flickering issues in 60Hz SST mode are further encouraged to obtain newer display firmware from their monitor vendor that will resolve flickering at its origin.

Users are additionally advised to utilize DisplayPort-certified cables to ensure the integrity of the DisplayPort data connection.

NVIDIA recently made new WHQL drivers available for users that have upgraded to Windows 8.1. The new drivers are version 326.01 and fully supports Windows 8.1. A full change log of the drivers has not yet been posted, but the 326.01 WHQL is likely very similar to the recent beta version, but with certification to work with the latest service pack/update to Windows 8.

The new 326.01 drivers are available via Windows Update or from the NVIDIA website. Supported GPUs include both desktop and notebook models from the 8000-series to the latest 700 series. Download links are below for the desktop and notebook drivers, depending on your bit-ness of Windows 8.1.

AMD announced two new drivers today, the final WHQL build of the 12.6 beta that many are currently using as well as a new beta version of 12.7. These represent the first new drivers on AMD's new release schedule, instead of a new driver every month they plan on now releasing a new driver once it has been proven to improve performance and been fully tested. The 12.6 offers the same benefits as the 12.7, the difference is that the 12.7 introduces a new feature called the Video Codec Engine which is designed to provide powerful GPU support for video encoding tasks in applications such as vReveal and ArcSoft MediaConverter. Check out AMD's blog post here for more details and scroll down to read the highlights of the 12.6 WHQL driver.

Resolved issues in AMD Catalyst 12.6 WHQL and Catalyst 12.7 Beta

Using AMD Radeon HD 7900 and AMD Radeon HD 7800 Series in TriFire or QuadFire configurations with AMD Eyefinity will no longer result in a BSOD when launching a DirectX application.

Multi-display configurations will no longer BSOD at the desktop on AMD Radeon HD 7000 Series GPUs.

If you are running Windows 8 and an NVIDIA graphics card on a desktop machine then you should head on over to NVIDIA to grab the WHQL certified GeForce 302.82 for 32-bit and 64-bit versions of the pre-release OS. If you are on a laptop then NVIDIA suggests you should continue to use the 302.80 drivers for the moment.

You will see a new NVIDIA Control Panel page that allows you to set up stereoscopic 3D for 3D Vision. The drawbacks are few, the driver will request a reboot in order to finish the installation, which you should do whether you are asked or not, and there is an issue for users of the GT520 who enable FXAA via the NVIDIA control panel but other than those two addendum, NVIDIA posted no other known issues. As it is a WHQL version, you can expect it to be stable and to be around for a bit as the release date of Win8 slowly approaches.
